Abstract

The purpose of our work is to isolate and study the physicochemical properties of pectin substances (an acidic polysaccharide) isolated from the pursley medicinal plant (lat. Portúlaca olerácea) growing on the lower part of the Amu Darya. The article presents the results of the isolation and chemical study of pectin substances by paper and gas-liquid chromatography. It has been established that this carbohydrate complex is represented by pectin substances. Their qualitative and quantitative monosaccharide composition has been established. Pursley is a very promising pharmacological agent that can be eaten by animals and humans, as well as in medicine. The physicochemical parameters and monosaccharide composition of Purslane have been studied. According to chromatography, the monosaccharide composition consists of uronic acid, galactose, glucose, arabinose, xylose and minor amounts of rhamnose. The obtained pectin substances from the pursley plant belong to high molecular weight acidic polysaccharides, arabinoglucouranans. The molecular weight of pectin substances is 18.5 kDa. The relative viscosity of a 1% pectin solution is 1,3 Pa·s. The monosaccharide composition of pectin consists of galactose, glucose, arabinose, and xylose in ratios of 2.3:15.0:2.3:1.0 as well as galacturonic acid.
